3 Claims.

This invention relates to ironing machine rolls and more particularlyto' the provision in an ironing machine roll of an extension at one endthat will support; articles being ironed projecting beyond the end ofthe roll and thus prevent such articles becoming wrinkled.

It has been found, while ironing large pieces on an ironing machine ofsmall size having one or both ends accessible, that the ironed piece isallowed to project over the end of the roll. In so doing the ironedpiece becomes wrinkled as it bends over the end of the roll.

Among the objects of my invention is to overcome the above objections,and provide an iron- 16 ing machine roll whose article supporting lengthmay be increased or decreased at the will of the operator.

Other objects, advantages and capabilities will later more fully appear.

so My invention further resides in the combination, construction andarrangement of parts illustrated in the accompanying drawings, and whileI have shown therein a preferred embodiment, I wish it understood thatthe same is susceptible of modification and change without departingfrom the spirit of my invention.

In the drawings:--

Fig. 1 is a side elevation of an ironing machine showing in dotted linesmy extension for the roll II) in partially extended position.

Fig. 2 is a fragmentary side elevation of the ironing machine rollshowing my improved ex-. tension extended to a greater degree than inFig. 1.

III Fig. 3 is an end elevation of the ironing machine shown in Fig. 1and looking toward the end of the roll to which my extension is applied.

Fig. 4 is a. longitudinal cross-section, partly broken away, of theironing machine roll and my 0 improved extension therefor, the extensionbeing shown in its fully extended position.

Fig. 5 is a fragmentary longitudinal sectional view similar to Fig. 4,but showing the extension as being pushed into the ironing machine roll.

Fig. 6 is a transverse section taken on the line 66 of Fig. 4.

In order to prevent the wrinkling or otherwise mussing of the ironedpieces, particularly the larger pieces, such as sheets, tablecloths andthe like, I have devised and shown in the accompanying drawings anextension at the end of the roll that supports the projecting portion'ofthe ironed pieces in a substantially straight and continuous line withthe main roll, and which supports and carries the ironed work withoutwrinkling. As such an extension would be in the way when smaller piecesare being ironed, I have so formed this extension that it will bepreferably collapsible or telescopic with the main roll so that it maybe pulled out or pushed in at the 5 will of the operator and varied asto length within the limits of its adjustability.

Referring in detail to the drawings, the main roll I is provided withsemi floating mounting, the idle head 2 revolving on the supporting tub-1o ing 3, the ironing machine roll being secured to the idle head 2 inany suitable manner. Also fixed to the interior of the hollow ironingmachine roll and at a point inwardly from the idle head 2, is the drivehead 4 which is fixed to the 15 drive shaft 5, which drive shaft is inturn supported by the journal 6 at the inner end of the supportingtubing 3.

The drive head I is preferably positioned a sufficient distance inwardlyfrom the free end of the roll I to provide the necessary room for thetelescopic roll-extension attachment, which is designated generally asA, and which in the form illustrated in the drawings comprises twocylindrical sections I and 8, the latter being telescopically mounted inthe former.

The ironing machine roll I is provided at its extreme end with theannular ring 9, which reinforces the roll at that end and also serves asa guide for the telescopic roll extension. This ring 9 is only optionalas it is apparent that the extension could slide directly in thecylindrical shell of the main roll or in any other suitable form ofguiding means therefor. The annular ring 9, as shown, is provided withan annular recess I0 into which the top cover cloth II of the roll maybe tucked and secured, and thus the cover cloth be kept out of theoperating way of the telescopic extension. I

Sections 7 and 8 are provided with tapered portions I2 and I3,respectively, which, as seen in Fig. 4, cooperate to prevent section 8from being pulled entirely out of section I and also to eliminatelooseness of these parts when in extended position. Section 1 isprovided with a 5 stop spring I4 (see Figs. 4 and 6) which, when sectionI is pulled to its outer limit, will contact with the annular ring 9 toprevent section I from being entirely removed from the main roll I. Ifit is desired to entirely remove section 1 from the main roll this canbe accomplished by bending the spring stop inwardly until it clears theinner edge of the annular ring 9. This bending of stop spring I4 may beaccomplished manual y or by any other suitable means.

Section 8, as shown, is provided with a flange l5 projectingsufiiciently beyond the diameter of section 8 to limit the closingtravel of this section which, as seen in Fig. 5, will be accomplished byreason of flange l5 striking flange I6 of section I, flange 16 in turnstriking the annular ring 9. Flange i5 of section 8 has an opening ofsmaller diameter than the interior diameter of section 8, thus providingan available hand-hold to enable the extension sections to be pulledoutwardly into extended position.

While my extension device is shown in the drawings as consisting of twosections, it will be readily understood that the same could consist ofany other number of sections as desired, and when more than two sectionsare used similar tapered portions l2 and I3 may be provided for thevarious sections to operate in a similar manner to those-shown inconnection with sections 1 and 8.

Having now described my invention,

I claim:-

1. In an ironing machine roll having a hollow interior and an open end,a tubular extension slidably mounted in the hollow interior and movablein one direction into the roll, and in the opposite direction to projectoutwardly therefrom, and a stop member adjacent the inner end of thetubular extension to limit the extent of its outward movement, said stopmember comprising a normally sprung out finger movable inwardly whendesired to entirely remove the tubular extension from the roll.

2. In an ironing machine roll having a hollow interior and an open freeend, a tubular extension longitudinally slidable inwardly and outwardlyof the roll, an inwardly projecting stop projection within the open endof the roll, and a normally outward sprung finger adjacent the inner endof the extension to normally limit the extent of outward movement of theextension, said finger being movable radially inwardly of the extensionto clear the stop projection of the roll to permit the extension to beentirely removed from the roll when desired.

3. In an ironing machine roll having a hollow interior and an open end,an inwardly extending annular projection in said open end, a tubularextension telescopically slidable in the hollow in- I
